Full title: Crown-rump length (CRL) measurements in relation to gestational age (grey small hollow circles) with 3^rd, 50^th and 97^th fitted centiles (Panel A). Brown small crosses in panels B and C represents the INTERGROWTH-21^st project data for CRL from 9⁺⁰ to 13⁺⁶ weeks gestational age of the fitted equation of the mean and SD from panel A. Panel C shows the model fit relating GA and CRL (Approach 2).
